Troubleshooting
Check For Cr2032 Baeries
Using The Round Baery
Pack
Inside the battery pack is a symbol indicating
which side the (round) CR2032 battery should
be inserted. In this case, for the stacked
battery pack, ensure that BOTH batteries
have the “+” symbol facing upwards.
Check for AA baeries
using the AA baery pack
Inside the battery pack are symbols
indicating which direction the AA battery
should be inserted. The flat side of the
battery should be paired with the spring
side of the battery pack.
If the batteries have been installed
correctly and your kit still isn’t operating
correctly, the next step is to check the
wiring.
